powerpc: Use generic compat_sys_old_readdir
Use the generic compat_sys_old_readdir instead of the powerpc one which is almost the same except for the almost complete lack of error handling. Note that we can't just use SYSCALL() in systbl.h because the native syscall is named old_readdir, not sys_old_readdir.
